Would love to get something like that for my 33, but where do you start with finding someone to make it???

^^^ like wise id luv a splitter on my 33

I'm actually in the process of making a prototype for something similar for the R33. Give me a few more weeks and i'll post up a thread.

phil, u da man, we obviously have very similar taste in our skylines,

with ur proto type, try and make it extend back as far as practical under the car,

Edited by ahh 33 s2

Well that is basically what I have made :)

However f**k paying $1300 delivered for something that is universal and won't fit properly.

Mine is in aluminium and I am just getting it to fit properly using all factory mounts. The only thing that needs to be done is the mounts on the front bumper.

I was thinking once it is made, to send it to some one for moulding and get them to make it in carbon fibre with a bit of a curved lip (like the Abflug lip posted) if there was enough interest.

I'll try to take some pics, it's just a bit hard to get ones of it fitted on the car because i'm doing it in the garage on stands lol. I'll see what I can do.

But basically this is what it looks like. This was what I used as a guide to do one for the GTST (photo is of a GTR).

The purpose of it was for the following:

a) The factory plastic undertray has to many little spaces that when you drop a bolt are a pain in the ass to find! I'm sure you have all been there. So with it being completely flat it makes it very easy to find a dropped bolt/nut etc.

b) Aerodynamics....this is arguable but really, it can't hurt. And anything that helps me stick to the ground when doing stupid speeds is ok in my books.

c) Catches any drips of oil that would other wise end up on the garage.

d) Better protection from splashes of water/rocks into a detailed engine bay.

e) It's cool, was fairly easy to make and I like it :D

What you think?

yep thats how ive envisaged it, but with some way of getting to the sump plug for easy oil changes and possibly incorporate some air guides for brake ducting.

How were you thinking of including your front under canards in to this? I was thinking of a way to mount the canards above this alloy sheet and have the alloy become more of a splitter and come out past the front bar slightly, it would then protect the bottom of the canards and also allow it to have a black splitter lip that would tie the canards into the front bar... now just to figure out what to put between the canards in the middle of the front bar to fill the gap between the bottom of the front bar and alloy splitter, Im thinking fibreglass to join the canards together underneath...

Well if I just keep it as a flat sheet of aluminium I will just have it between the bumper and the canards which makes it easy to fit.

If we go with a carbon fibre one that incorporates a lip, than that will be a bit more tricky, but i'm up for the challenge.

My challenge at the moment is to mount it properly to the front bumper. Obviously you can't use a nut on the end of the bolt because you can't access it once the undertray is on. So i'm going to try and use those little c-clip things with a nut built into one side of them (can't for the love of god remember the name of them at the moment. I'm sure you know what I mean).

Sump plug is easy enough, just cut a small sqaure in the drain area (has to be a bit larger due to the angle the oil comes out at).

The rear of it also has a cut out so you can still put a jack under the subframe without denting the undertray.

Brake cooling guides is interesting, didn't think of that. Hmmmm i'll have a look to see what is possible.

yeh that look good phill, id def want mine to protrude past the front bumper even if its only by a couple of inches, with a nice radius to it, i also like on the jun design little guides to deflect air around the inside of the wheels,

i have been thinking of doing the same for a long time, but never seem to get any further then thinking about it. maybe PSI would be keen for another phil inspired design

Phil,you are bloody brilliant.

:D

    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
